Power Optimization Techniques in ARM-Based Embedded Systems

Abstract

Embedded and communication systems are becom- ing more widely used. This implies that we must figure out how to get them to function without consuming excessive amounts of energy. These days, ARM-based processors with a set of instructions known as RISC are highly popular due to their high performance and low power consumption. However, the tasks we want these systems to perform—such as communicating wire- lessly, joining the Internet of Things, and processing signals—are becoming increasingly complex over time. Because of this, it is challenging to maintain their energy-efficient operation.Power conservation in embedded and communication systems remains a concern. This study examines power management strategies for ARM-based devices. Three aspects are the focus of the research: power consumption, memory utilization, and performance. To research these topics, we employ simulations. We experiment with ways to enhance performance, like employing unique low- power modes, streamlining instructions, and better organizing data. The goal is to observe how every modification impacts the system, particularly in ARM-based systems.
